Tire Pressure Control (RDC)
*
Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, there is an
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire
* is
provided for temporary use only in
the case of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire
* that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will also be monitored once the
tires have been mounted and the sys-
tem activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your authorized BMW center has been
trained to work with the RDC system
and is equipped with the necessary
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or
devices which use the same radio fre-
quency.
The indicator lamp will come on with
a yellow lamp during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your authorized BMW
center for additional information.

To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. BMW tests and approves
wheel/tire combinations. Refer to
page 117.
Do not use retreaded tires, since
driving safety may be impaired by
their use. This due to the possible varia-
tions in casing structures and, in some
cases, to their extreme age, that can
lead to a decrease in their durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 129 indicates that the tire was
manufactured in Week 12 of 1999.
BMW recommends the replacement of
all tires when the tires are no more than
6 years old, even if a tire life of 10 years
is possible.
Spare tires over 6 years old should be
used only in case of emergency. Such
a tire should be replaced by a new tire
immediately, and should not be fitted
together with new tires.
Between the axlesThe tread wear patterns at the front end
differ from those at the rear – the actual
patterns will vary according to individ-
ual driving conditions. In the interests of
safety and maintaining optimal handling
characteristics, tire rotation is not rec-
ommended.
If a proposed interaxle rotation of tires
is based on economic considerations,
one should consider whether the costs
for the rotation are likely to be recap-
tured by any increase in the service life
of the tires which might be realized.
In principle, interaxle rotation should be
performed in short intervals, with a
maximum of 3,000 miles (5,000 km).
Consult your authorized BMW center
for more information.
Should you decide to rotate the tires, it
is essential to comply with the following:
Rotate tires on the same side only, since
braking characteristics and road grip
could otherwise be adversely affected.
Following rotation, correct the tire infla-
tion pressure.
If different tire sizes are mounted
on the front and rear axles (refer to
page 117), the wheels may not be ro-
tated from one axle to the other.<

Changing tires
Take these precautionary mea-
sures if you have either a flat tire
or are changing the tire:
Park the vehicle as far from the flow of
traffic as possible and on firm ground.
Switch on the hazard flashers. Turn the
steering wheel to the straight-ahead
position, remove the key and engage
the steering lock. Shift into 1st or re-
verse (selector lever in "Park" with auto-
matic) and engage the parking brake.
All passengers should be outside the
car and well away from your immediate
working area (behind the guardrail, for
instance).
If a warning triangle or portable hazard
warning lamp is available, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface that is not slippery. Avoid jack-
ing the car on a soft or slippery support
surface (snow, ice, loose gravel, etc.),
as it could slide sideways.
Ensure that the jack is positioned on a
solid support surface.
Do not place wooden blocks or similar
objects under the jack. If this done, the
jack might not be able to reach its full
support capacity because of the limited
height.
Do not lie under the vehicle or start the
engine when the vehicle is supported
by the jack – risk of fatal injury.<
Your BMW has either a spare
* or
space-saver tire
* for temporary use and
to ensure your mobility.
Take the luggage compartment
floor panel completely out to
remove the spare tire
* (refer to
page 41).<

Procedure1 Please observe the safety precaus-
tions stated on the previous page
2 Secure the vehicle against rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If
the vehicle is parked on a down-
ward slope, place the wedge se-
curely in front of the tire. If the
wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure the
vehicle from rolling
3 Wheels with full wheel covers:
Reach into the ventilation openings
and pull the cover off462de251
4 Loosen the lug bolts 1/2 turn
5 Place the jack under the jacking
point nearest the wheel you are
changing (refer to the illustration at
the left) in such a way that the base
of the jack is positioned vertically
under the jacking point relative to
the entire surface, and that the jack
head fits securely into the square
recess of the jacking point (refer to
illustration detail) when the jack is
cranked
6 Crank the car up until the wheel in
question is raised from the ground
7 Unscrew the lug bolts and remove
the wheel
8 Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub; clean the lug
bolts462de252

one another
462de266
13 If your wheels are equipped with full
wheel covers
*: Position the wheel
cover with the valve opening over
the valve (arrow) and press it onto
the wheel with both hands
14 Inflate tire to the proper pressure as
soon as possible.
For vehicles with RDC Tire Pressure
Control
*:
Reactivate the system after mount-
ing either the spare tire or after in-
flating tire to proper pressure.
(Refer to page 82).
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire
*, since this
could damage the cover.<
462de279
The vehicle jack is designed for
changing tires only. Never use it to
raise another vehicle model or any load
of any kind, as this could lead to acci-
dents and personal injury.
Have the lug bolts checked for proper
tightness with a calibrated torque
wrench at the earliest possibility [torque
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, take care to
ensure that you do not damage the re-
taining pin in the spare tire recess.
If light-alloy wheels other than Original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as quickly as
possible and have the new wheel bal-
anced.
For black-painted aluminum wheels
*,
use only those balancing weights ap-
proved by BMW for use with light alloy
wheels. Never attempt to balance these
wheels using standard balance weights.

Changing tires Battery Driving with the space-saver
spare tire
*
Drive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted. Mount a wheel
and tire with the same size and specifi-
cations as the others at the earliest
possible opportunity. Maintain correct
tire pressures. Refer to page 28.<
Battery location The battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41), and give a screwdriver or a
coin a 1/4-turn counterclockwise to
release the two fasteners plus an addi-
tional fastener in the upper-center side
trim panel. In order to remove the stor-
age tray, slide the side trim panel
slightly upward.460de176
